Be it known that I, ROBERT TALMADGE, of Coshocton, in the county of Coshocton and State of Ohio, have invented certain new and useful Improvements in Washing-Machines; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure 1 is a side elevation Fig. 2, a section through line x x, Fig. l; Figs. 3 and 4, views of the devices for attaching the machine to the tub; Fig. 5, a top view of one end of the base of the frame, showing its application to one of the sockets; Fig. 6, a longitudinal section of the lower roll, and Fig. 7 an end view of one of the uprights.

Similar letters of reference in the accompanying drawings denote the same parts.

My invention has for its object to improve the construction and efficiency of washingmachines; and to this end it consists in a luted convex roller, combined with a smooth concave roller in such a manner that the clothes to be washed are acted upon with a yielding pressure, and as they pass between the rollers are subjected to a rubbing action, and drawn toward the centers of such rollers, to prevent the clogging of the machine.

In the accom-panying drawings, A A are the uprights,- B the base, and C the top crosspiece, of the roller-frame, constructed in any preferred manner of wood or metal. D is al large convex fluted roller, having its bearings in the base of slots E E, formed in the uprights A, and F is a small concave roller, having its bearings also in the uprights, and arranged beneath the fluted roller, so as to receive the pressure thereof.

G Gr are half-boxes, fitting the tops of the uted roller-journals, and provided with stems H, which extend upward through a pressurebar, I, and the cap-piece of the frame.

The stems are surrounded by helical or spiral springs J, between the pressure-bar and' top piece, and the pressure-bar is operated to increase or decrease the tension of the springs, and, therefore, adjust the pressure of the roller by means of the thumb-screw K, as shown.

L L are metal plates secured to the outer prights,1"soas`t slightly-ove ap the edges of the slots, for the purpose of holding the half-boxes in place, and preventing the roller-journals from wearing the slots.

One of the journals of the luted roller is extended to form the crank M, for operating the machine, as shown in the drawings; or the crank may be'made separate, and attached to one of the journals, as preferred.

N N are concave bars or blocks interposed between the concave roller and base of the frame, for the purpose of guiding the clothes between the rollers, and preventing them from being carried around and woundabout the lower roller.

The machine thus constructed is attached to an ordinary wash-tub in the following manner:

The base of the frame is provided with a tenon, O, on one end, adapted to t within a socket, p, secured to the inside of the'tub, and this socket is formed with a bottom aud two side ilanges forholding the tenon in place.

Q is a second flanged socket, attached to the j inside of the tub, to receive and support the opposite end O of the base-piece, and R is a stud or'pin driven into the end of the basepiece, and adapted to fit within the vertical slot ofthe socket Q. In introducing the frame into the tub the end Ol ot' the base-piece is rst inserted within its socket and held below the opposite end. rlhe latter is then introduced within its socket and pressed down into place, as shown, the vertical slot in which the piu works allowing this movement to be easily accomplished.

When the machine isin operation the clothes are passed between the two rollers, and since the diameters of each are varied the lower concave roller acts as a guide or support for the clothes, while the upper fluted roller operates upon them with a rubbing action similarvto that produced by rubbing the clothes upon the common corrugated hand -board. The degree of pressure with which the upper roller shall bear uponv the clothes is regulated by adjusting the pressure of the springs, as above described. By this means the clothes are thoroughly washed," and cleansed with but little expenditure of time and labor.

The concave vand convex forms given to the two rollers tend to draw the clothes' toward the centers of each, and therefore prevent them from beingr carried to the sides or up-l rights ofthe frame to clog the machine.

This tendency of the clothes toward the lcenters of the rollers is assisted materially by the Weight of the former, as will be readily understood.

I am aware that it is not new to flutewthe rollers of a washing-machine, and I am also aware that a machine has been made with rollers having a convex surface, for the purpose of carrying a band on which the clothes were moved along. My invention therefore is an improvement, in which a iiuted convex roller actspin conjunction with a smooth concave roller. The duting in this construction assists in lcarrying the clothes along', and the convex'form of the carrier drawsfthem from the ends of the roller toward the center. The

yconstruction is a simple and cheap one, and
